Lysis timing and bacteriophage fitness.
The effect of lysis timing on bacteriophage (phage) fitness has received little theoretical or experimental attention. Previously, the impact of lysis timing on phage fitness was studied using a theoretical model based on the marginal value theorem from the optimal foraging theory. An implicit conclusion of the model is that, for any combination of host quantity and quality, an optimal time to ...
متن کاملFactors in lysis and lysis inhibition by lambda bacteriophage.
Groman, Neal B. (University of Washington, Seattle). Factors in lysis and lysis inhibition by lambda bacteriophage. J. Bacteriol. 90:1563-1568. 1965.-Induced Escherichia coli strain K-12(lambda112) exhibited lysis inhibition at 37 C but lysed at 44 C when incubated in LB medium lacking NaCl [LB - (NaCl)]. In LB medium containing NaCl, the temperatures for lysis and lysis inhibition were reverse...
متن کاملBacteriophage adsorption rate and optimal lysis time.
The first step of bacteriophage (phage) infection is the attachment of the phage virion onto a susceptible host cell. This adsorption process is usually described by mass-action kinetics, which implicitly assume an equal influence of host density and adsorption rate on the adsorption process. Therefore, an environment with high host density can be considered as equivalent to a phage endowed wit...
متن کاملLysis of lysis-inhibited bacteriophage T4-infected cells.
T4 bacteriophage (phage)-infected cells show a marked increase in latent-period length, called lysis inhibition, upon adsorption of additional T4 phages (secondary adsorption). Lysis inhibition is a complex phenotype requiring the activity of at least six T4 genes. Two basic mysteries surround our understanding of the expression of lysis inhibition: (i) the mechanism of initiation (i.e., how se...
متن کاملThe Growth of Bacteriophage and Lysis of the Host
1. A new strain of B. coli and of phage active against it is described, and the relation between phage growth and lysis has been studied. It has been found that the phage can lyse these bacteria in two distinct ways, which have been designated lysis from within and lysis from without. 2. Lysis from within is caused by infection of a bacterium by a single phage particle and multiplication of thi...
